Paper Abstract

This work presents results of purification process investigations from undesirable contaminations as iron, copper etc. oxides of porous preforms from SiO2 at utilization of different chlorine components in high temperatures. We defined sources of undesirable contaminations during silica glass synthesis by colloidal sol-gel methods. We calculated equilibrium constants of chemical reactions of transient element oxides with three different chlorinating agents under high temperature conditions. Then we examined possibilities of removing these contaminations. Results of presented investigations permit on projecting variant of colloidal sol- gel method making possible receipt glass about optical fiber purity.
